I am creating a native wood in my back garden. I have 4 x 4 m to play with I am wondering what density of trees and shrubs I can use for canopy and shrub layers. eg. Canopy trees 2m apart and shrubs in between at say 1m apart?
I have to train a large Virginia creeper up a wall but I can't screw anything into the wall as it is hollow (I think it's externally insulated). Is there any clever method for attaching something to the wall that the climber can then use?
